Power Transformer

Product Range

• Upto 10 MVA 3 Phase 11 & 33kV Class

Standards

SURYA's transformers are designed and tested as per IS : 2026, BS - 171, IEC - 76 & IEC - 726.

Vector Group

Transformers will be connected as per vector group reference Dyn11. Other vector groups can be offered as per specific requirements.

Terminal Arrangement

H. V. - Bare Bushings or Cable Box, L. V. - Bare Bushings or Cable Box. Disconnecting chambers can also be provided on both HV and LV Cable boxes.

Temperature Rise

SURYA's transformers are designed for a maximum temperature rise of 40 / 50 degree C of oil / winding. Lower temperature rise can be offered on request.

Unitized Substation

The unitized substation is a state-of-the-art system which simplifies conventional substation design. SURYA’S fully engineered factory built design, is tailor made to customer needs. the company takes the total responsibility of engineering and building the complete USS are subject to stringent internal quality checks. The housing is made from a composition of sheet steel having thickness of 2mm,1.5mm mild steel and 4mm structure member base frame and then power coated.

Unitized substations may be indoor or outdoor, with a selection of high - voltage incoming sections, a choice of transformers types and an arrangement of switchgear to suit the application. Most switchgear to suit the application. Most switchgear assemblies are configured as unit substations. Unitized substation follow the system concept of locating transformers as close as practicable to areas of load concentration at utilization voltages, thus minimizing the lengths of secondary distribution cables and buses.

Features of united substation transformers

• Specific arrangements of switchgear minimizes installation expenses.
• Lengths of cables and buses are minimized, reducing the likelihood of faults and improving voltage regulation.
• Wide choice of components and ratings to meet exact application requirement allows for extreme flexibility.
• Complete coordination, both mechanical and electrical ,provides for improved service continuity.

Salient Features

• Compact in construction, occupies less floor space and does not effect the elevation of commercial complex.
• Easy to operate and maintain
• In accessible to live parts.
• Fully compartmentalized design.
• Substation housing is divided into three compartments i.e. the HV compartment ,the transformer compartment and the LV compartment
• All fastness are SS/Steel Zinc plated.
• The roof is special, heating due to solar radiation is minimized by the use of double skin roof and having slanted top. Air insulates the substation from the effect of sun radiation and specially designed ventilation opening facilitate air circulation, thereby supporting complete cooling system.
